System for charging a vehicle battery

Abstract

Disclosed is a device for fast charging a battery, with two inverter circuits, which are each electrically connected to a three-phase electric motor, the battery being electrically connected on the one hand to an inverter plus and on the other hand to an inverter minus of the inverter circuits, and with a charging voltage connection, the positive terminal of which can be connected to a multi-way switch, and the negative terminal of which can be connected to the inverter negative of both inverter circuits or to a further multi-way switch, wherein the inverter positive of the two inverter circuits can be electrically connected via the one multi-way switch, at least one inductor of one electric motor can be electrically connected, and via one multi-way switch or via the other multi-way switch at least one inductor of the other electric motor can be electrically connected.
